The metal net with the subject innovation is in the bangbeomchang using a metal net having a repellent function, bending at the edge end portion; Window frame part of the metal net, including the bent portion is inserted into the coupling groove is provided; And the coupling and a portion of the metal net, including parts of the bending to be inserted into the grooves containing the binder member of the binding to the window frame, one side of the upper and lower cut surfaces of the engaging groove of the saw blade protruding blade type is provided, the other side a plurality of concave and convex for friction to increase the friction with a metal net is provided, which at one side of the cutting plane upper and lower sides of the engagement member is reverse saw blade projections in which the saw blade projection and binder is provided, the other side to raise the metallic screen and the frictional force a plurality of friction projections are provided, whereby additional deflection of the wire mesh by a secondary fixation by a friction force applied to the saw blade protruding primary fixed and the metal mesh with the engagement member of the metal mesh is firmly in the window frame by providing bangbeomchang using a metal net, it characterized in that the coupling, it is possible to easily secure the metal mesh to the window frame, More may be bangbeomchang is provided with a metal net, which is more reliable.
